then what is the chemical equation for the bleaching of a stain?Do stain has chemical formula.. See, now that's a hard one to be sure. they should have given you more info. Could this have been an example from your textbook? Did they describe how bleach works? Could you just assume ...
In this equation: Sodium hydroxide (NaOH) reacts with chlorine gas (Cl2) in the presence of water (H2O). The result of the reaction is the formation of sodium hypochlorite (NaClO), sodium chloride (NaCl), and water (H2O). Sodium hypochlorite (NaClO) is the active ingredient in bleach re...
What is the chemical formula of the compound that is made up of strontium and oxide ions? What is the name of the following chemical formula Cr(BrO_3)_2? What is the formula for the hydrogen sulfate ion? What is an ionic equation?
Step 3: Verify that the equation is balanced Since there are an equal number of atoms of each element on both sides, the equation is balanced. 3NaClO +6HCl +2Al =2AlCl3+3NaCl +3H2O NaClO-++HCl-++Al-+ = AlCl3-++NaCl-++H2O-+ ...
